In New York this s probably not far out of line.I do recommend getting at least 3 estimates though if you do not have a regular ac guy you trust as prices will vary among contractors even in same city due to each companies overhead and operating cost.

The basic wholesale cost of the 3 ton 16 SEER system is in the low to mid 3000 depending on company's buying power.

AS a rule of thumb you should expect to pay double wholesale cost for equipment with installation. So a fair price can be as low as 6K depending on companies necessary markup.
